Bingo. I lost over 100 pounds6 years ago. How did I get that big? I put on weight very easy. I have to be careful what I eat. In high school and college I ate what I wanted but I mowed grass and did yardwork to make money. So I burned off everything I ate. Well got married ate like I did before so I gained. Now I eat right and excercise hitting 40 and feeling great. Breakfast is the single most important meal to losing weight and maintaining. And keeping adult beverages to a minimum.
I see your post about egg whites and oatmeal. If I remember correctly, the oat grain, as in oatmeal, is very low in carbs compared to other grains such as wheat and rye. As it happens, I LOVE oatmeal (I'll eat it dry right out of the container or pour it dry into a bowl and add milk when I'm too lazy to cook it ... I eat a LOT of oatmeal), so my "carb" fix tends to be low carb anyway. If you're interested, I have a FABULOUS recipe for buttermilk oatmeal pancakes, high in calcium, D, and relatively high in protein, as well as low-carb and filling.
With regard to the egg white ... I have a pretty good track record with predictions. I KNEW that the ridiculous "eggs are bad for you" thing was wrong from the git-go, and so did the wiser (and healthy, trim) elders in many generations of family. I knew that hydrogenated vegetable oil (shortening, margerine) was worse for you than butter or lard YEARS before that truth was made public, back when they were promoting the health benefits of stuff like Crisco and margerine!!!! Like doctors promoting smoking on TV in the 50s! High-numbered sun screen, importance of dairy for those who can handle it (there, genetics really DO come into play RE lactose intolerance) and the foolishness of thinking that soy can substitute for animal protein ... I trust my hunches because they've been right.
My hunches tell me that while in the short run it looks smart to toss the yolk and eat only the white, that in a decade or two, they're going to say (officially ... wouldn't surprise me if it was already known but too unpopular to publicize, as with the hydrogenated vegetable oil thing) that you need the whole package -- the yolk and the white -- to get the maximum nutritional benefit that is balanced to work best. I have a hunch that the protein you get from the egg whites is missing something provided in the yolk, and that the body metabolizes it less efficiently than it would otherwise. Just a hunch. EAT THEM YOLKS!!! Trust God and nature to have put it together in the best package. HE knew what He was doing.
